DALLAS (CBSDFW.COM) – A Dallas teenager is recovering in Houston following a lung transplant. Marcos Saldana has battled cystic fibrosis for the past 11 years. A transplant was the 14-year-old’s only option. It took him just one day to find a match. As the teen recovers in Houston, his friends in Dallas have organized support for him and his family.

Even in the midst of a daunting recovery, Saldana wears a big smile. His friends said that is just who he is. “He’s always been very nice,” childhood friend Ryan Stansbury said. “He’s never been mean or said anything bad about anyone. He’s just a nice guy.”

Life has not been easy for the Dallas teen and Woodrow Wilson High School freshman. Over the past three years, his health began to deteriorate from his condition. Yet just last week, Saldana had a life-changing transplant. A match was found for him the very next day after his name was placed on the donor list.

“It’s a miracle,” family friend Sandy Stansbury said. “I just strated crying. I just couldn’t believe it, that it happened so quickly. Then, everything worked so well. It was successful. It’s a perfect match. He’s recuperating so quickly.”

Saldana remains at Texas Children’s Hospital in Houston recovering from his surgery. He will remain in Houston for the next three months.

Meanwhile, back in Dallas, Saldana’s friends have made a ‘get well’ video, and three different Facebook pages have been created for him and his recovery — a stong showing of support with the hope that it helps heal their friend and brings him back home soon.

“He’s been sick a long time,” Ryan said. “We’d go and visit him in the hospital, but it’s good he won’t be that bad anymore. I’m happy for him.”

“Lots of prayers, lots of financial support,” Stansbury said. “People have already gone down to visit, just wanting to do whatever we can.”
